Scientists map changes in soot particles emitted from wildfires

Not many people would voluntarily fly through plumes of smoke emitted from wildfires. But atmospheric scientists from the U.S. Department of Energy's Brookhaven National Laboratory do, over and over, tracing flight paths that might make ordinary air passengers sick. Their goal? Measure properties of the soot particles emitted by wildfires so they can learn how these plumes affect Earth's climate.
